SCUBA & Bodybuilding?

The other day my wife asked me if I am getting bigger.

At first, I brushed it off. I haven’t had time to go to the gym and I haven’t been working out much at home, so I really can’t be getting bigger.

On the hand, if anyone were to notice such a thing, it would be my wife. 

So that got me thinking. What is the relationship between scuba diving and bodybuilding? We learn in scuba diving that nitrogen retention is very bad, but we learn when bodybuilding that nitrogen retention is very good.

A quick search online suggested the two are unrelated. However, everything I found was about the safety of nitrogen-retaining bodybuilding supplements and scuba diving. There was nothing about scuba-related nitrogen retention and its effects on bodybuilding, nor was there any evidence that any of these forum commenters have any idea what they are posting about.

In other words, I found nothing at all about scuba-related nitrogen retention and bodybuilding. All I have is one unscientific comment from my wife, so my quest for answers continues….
